Abstract

The invention discloses a waterproof flame-retardant acoustic panel and a production process thereof. The waterproof flame-retardant acoustic panel comprises the following raw materials in parts by weight: 40-60 parts of gypsum powder, 15-35 parts of bamboo carbon fibers, 10-20 parts of polyester fibers, 8-15 parts of glass fibers, 6-10 parts of attapulgite, 5-15 parts of blast furnace slag, 3-8 parts of calcium hydroxide, 1-5 parts of magnesium oxide, 0.5-3 parts of an inorganic adhesive, 1-3 parts of a water repellent and 0.5-1.5 parts of a flame retardant. The production process of the waterproof flame-retardant acoustic panel comprises the four steps of purification of attapulgite, preparation of a matrix material, preparation of a molding blank and natural curing. The waterproof flame-retardant acoustic panel is safe and environment-friendly in component, good in waterproof and flame-retardant effect, and resistant to sound and heat, and maintains the strength and the hardness of a gypsum board.

Description

technical field [0001] The invention relates to the field of decorative materials, in particular to a waterproof and flame-retardant sound-absorbing board and a production process thereof. Background technique [0002] Sound-absorbing panel is an ideal sound-absorbing decorative material, which has the advantages of sound absorption, environmental protection, heat preservation, moisture resistance, mildew resistance, easy dust removal, easy cutting, mosaic, simple construction, good stability, good impact resistance, and high cost performance. There are a variety of colors to choose from, which can meet the needs of different styles and levels of sound-absorbing decoration. Among them, gypsum board is a commonly used sound-absorbing board, which is widely used in building decoration materials because of its light weight, high strength, sound insulation, heat insulation, fire prevention, and easy processing. [0003] The invention patent of authorized notification number CN ...
